Salmonella typhi disease in HIV-infected patients: case reports and literature review.

Two patients with AIDS and severe immunodeficiency developed typhoid fever. The diagnosis was confirmed by isolation of Salmonella typhi from blood cultures, while Widal's serum test isolates proved in vitro sensitive to all tested antimicrobial agents, and complete recovery was obtained with i.v. cotrimoxazole and piperacillin treatment. Unlike complications by non-tiphoid Salmonellae, S. typhi infection has been infrequently reported in the context of AIDS: to our knowledge, only five cases of typhoid fever have been described in HIV-infected living industrialized countries. Medical history and epidemiological information may play an important role in prompting the search for an S. typhi infection in patients coming from endemic regions, since most of the sign and symptoms of typhoid fever may mimic those of a sepsis.
